Newark Liberty, one of the USA's most congested airports, says it will be the first major domestic airport to test a new navigation technology aimed at reducing flight delays. Ground Based Augmentation System uses global-positioning satellites to spot planes rather than the radar-based system currently in use. The airport says the system will enable planes to fly closer together without reducing safety.

American Airlines, the world's largest carrier, last week opened the final phase of its massive new terminal at New York John F. Kennedy. The $1.3 billion, 36-gate terminal, parts of which have been used since 2005, dramatically expands American's capacity at one of its busiest airports.
